About Jumpin' Jack

Jumpin' Jack is a remastered emulated version of the 1983 ZX Spectrum arcade-style platformer. You guide Jack through 20 increasingly challenging levels.

Complete each level

Jack must jump through gaps in eight layers to finish a level. The gaps appear at random and move across the screen, so you need to time each jump carefully. Later levels add more hazards to dodge.

Modern features

The remastered version lets you save or load the game at any point, remap controls, and choose image scaling and smoothing options. It also supports most modern game controllers.

Frequently asked questions

Steam lets publishers create keys to sell in other shops. Once you activate a key, the game is yours to keep, just like a store purchase.

Disclaimer: CD keys have an inherent 1–2% average failure rate. Check the shop terms for buyer protection info. Steam offers no buyer protection for keys bought in other shops and doesn't refund them.
